CVE-2013-4082

Description

The vwr_read function in wiretap/vwr.c in the Ixia IxVeriWave file parser in Wireshark 1.8.x before 1.8.8 does not validate the relationship between a record length and a trailer length, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) via a crafted packet.
